Detail Drawing

Chapter 4: Detail Drawing

Now that we have completed modeling the components, the next logical

step would be to assemble them, and this is what is usually done at this point in

the design. However, we are going to make their 2D detail drawings instead.

The reason we are doing this is to show additional functionality before

jumping into assembly modeling, including understanding component

configurations, and later in the assembly lesson the effect of modifying a

component in the assembly and propagating those changes back to the part and

its corresponding drawing.

In most modern design software packages, including SOLIDWORKS, the

3D models are created first, and from them a 2D manufacturing drawing is

generated. By deriving the drawing from the solid model, the 2D drawing is linked

and associated to the 3D model. This means that if the part is changed, the drawing

will be updated and vice versa. In SOLIDWORKS, 2D detail drawing files have the

extension * .slddrw and each drawing can contain multiple sheets; each

corresponding to a different printed page of the same or different 3D models (parts

and/or assemblies).

SOLIDWORKS offers an easy to use environment where we can quickly

create 2D drawings of parts and assemblies. In this section we'll cover Part

drawings only. Assembly drawings will be covered after the assembly section. We

will add all the different model views, annotations, dimensions, section and detail

views necessary for a manufacturing department to fabricate the component

without missing any details. In this section we will also introduce a new concept

called Configurations, which allow us to have similar but different versions of the

same part using the same 3D model, for example, a version of the part as it comes

out of a foundry and a version for the machine shop with all the details to machine

the finished part.

IMPORTANT: 2D detail drawings can be made using any of the many

dimensioning standards available in the industry. In this book we will use the ANSI

standard. After, or while creating a detail drawing, the dimensioning standard can

be easily changed to a different one by going to the menu "Tools, Options" and

selecting the "Document Properties" tab. In the Drafting Standard section, a

different standard can then be selected. It is important to note that after changing

to a different standard, SOLIDWORKS updates the dimension styles, arrowhead

type, etc. accordingly. For more information about changing units and

dimensioning standards see the Appendix.
